Months later, following Aspheera's defeat, she is imprisoned for her crimes and placed in cell one. She receives a visit from Wu, where she reveals she'd banished Zane to the Never-Realm, taunting the "Treacherous Deceiver" with his student's fate.
At least a year later, the Ninja decided to free Aspheera from her incarcenation from the cell in exchange for removing Nya's elemental power to revert her back to her human form. While helping her escape, Zane's laser device accidentally tripped from him, resulting into it accidentally shooting at the cell's pole and causing the structure to fall and destroy.
Shortly after Lloyd defeated Garmadon, he was placed in Cell One in order to prevent him from escaping.
Noble shows Lloyd to Garmadon's wing, stating it was built just for him. After unlocking the entrance, he runs off, leaving Lloyd to confront Garmadon by himself. When he reminds Garmadon that he had requested to see Lloyd, Garmadon claimed that it was unusual. When Lloyd threatened to leave, Garmadon remembered and told him that the Bringers of Doom were coming and that although he didn't care, he would rather not be destroyed along with Lloyd. He said that he had decided to help the ninja defeat them and that he was the only one powerful enough to do so. Lloyd refuses his offer and angrily storms off, but Garmadon assured him that he will come back.
After failing to stop the Oni, the ninja return and free Garmadon, fearing he is the only way to defeat the Oni.
After the defeat of the Pyro Vipers and Zane's presumed death, Aspheera was placed in cell one and was later visited by Wu, to whom she remarked that this is just like their last encounter. Wu, disgusted by her actions, told her that Zane had no part in this, and questioned if she was satisfied with her deed. However, Aspheera says that she only wanted revenge on him by trapping him, making suffer the way she did and that Zane was actually banished to the Never-Realm. Once Wu left in horror, Aspheera taunted him while laughing hysterically, asking what he would do now.
After Mayor Ulysses Trustable refused to release Aspheera from Cell One, the Ninja had no choice but to do it themselves. While half of them infiltrated to Borg Tower to get Aspheera's staff, the other half infiltrated to Kryptarium and into Cell One, making the deal with Aspheera to free her in favor of removing Nya's elemental power, to which she eventually agreed. While escaping through the cell's pole, Zane's laser device tripped and fell on the floor, causing it to shoot to the pole and destabilizing it, resulting into the cell to separate and fall to the deep floor and get destroyed.

- Cell one is very similar to the cell in the Crystal Cove Animal Asylum for the Criminally Insane where Professor Pericles was locked in Scooby-Doo! Mystery Incorporated.
- These cells resemble bell jars, especially with the "knob" or loop at the top.
- The cell contains a sink, bed, table and chair, all made probably of metal.
- In Season 11, the dome of the cell is slightly lower than in Season 10, as well as wider.
- It is unknown where the inhabitants of the cell go to the toilet, because the cell itself does not contain it.
